The fact that the conversation in the poem takes place in a telephone box serves to increase the sense of isolation and disaffection of the speaker. There is, however, a deeper meaning than the one conversation. The poem could be said to be about the wider human experience of miscommunication and alienation - experiences that go beyond those of a phone-call but that can happen when you are speaking to someone in the flesh. With human interaction there often comes a large or small level of evasiveness and a lack of complete honesty. People also understand and interpret one another's words in terms of their own experience (ego if you like) and their own particular state of mind at the time the interaction takes place. We also look for hidden meaning in one another's words using the tools available to us - reading of facial expressions, what we know about the speaker and their history etc. All this means that even when you are talking face to face there is plenty of room for misunderstanding, misinterpretation and consequently alienation.
I chose the vehicle of the telephone call to convey this idea of how humans have trouble communicating with one another - the telephone box itself reinforces the idea of separateness, how ultimately we are all alone.
